Aprilaire E070 - Operating the Dehumidifier

ENERGY SAVINGS TIPS
ENERGY SAVINGS TIP #1:
Adjust the humidity setting to be as high as is comfortable
to reduce dehumidier run time. If it feels clammy or “smells
musty,” lower the humidity setting� To save energy, turn the
dehumidier to OFF when you open your windows, just as you
would with air conditioning�
ENERGY SAVINGS TIP #2:
If vacating your home for an extended period in the summer,
set the RH at 55% and set your thermostat as high as you are
comfortable setting it to in the cooling mode� This will keep the
humidity at a controlled level while minimizing the amount of
cooling energy used�
OPERATING THE DEHUMIDIFIER
1. If equipped, use the ON/OFF Power Switch, located by the
power cord, to apply power to the dehumidier.
NOTE: The unit can remain plugged in with the ON/OFF Power
Switch on (if equipped) unless the unit will not be used for an
extended period. Use the ON/OFF Button on the user interface to
turn the unit off for short durations. When the unit is idle (neither
the fan nor the compressor running) the unit will use less than
3W of power�
2. Use the ON/OFF Button (see FIGURE 2) on the user interface to
turn the dehumidier ON. The rst press of a button will turn
on the display light, so if the display was dark, you might
need to press it again. Once ON, the display will show the
current dehumidier setting.

3. The dehumidier blower will turn on, the word SETTING
disappears from the display, and the words AIR SAMPLING
appear (see FIGURE 3). This wording indicates that
the dehumidier is sampling the air to determine if
dehumidication is needed and shows the measured
humidity level�
If the control is already ON, lowering the setting will initiate
air sampling�
4. After sampling the air for 3 minutes, if the Relative Humidity
(RH) is above the setting, the compressor turns on to
dehumidify the space� The word DEHUMIDIFYING appears
when the compressor is turned on (see FIGURE 4).
